IMPROVED RAILWAY-GAB courmwe.

The Schedule referred to iii-these Letters Patent and making part of thesame.

- To all whom it may concern} tion and operation of the same, referencebeing had to the accompanying drawings, making a part of thisspecification, in which-- I Figure 1 is a perspective view.

' The nature of my invention consists in supporting the notchedcoupling-pin by means ofaslide, as shown in the figure, which shall bedriven from its support when it comes in contact'with the other car,which will allow the pin to drop' through the link, thus securing aself-coupling, which will materially reduce expenses, and entirelydispense with the danger of carcoupling.

The coupling-pin B is provided, near its lower end, with anotch, B, bymeans of which, as long as the pin is in the narrow part of the openingin the slide, it is supported in an elevated position, without danger ofaccidentally dropping before the proper moment.

I make the slide of sheet-iron or heavier material, as the case mayrequire, and in the form as represented at A. a

The front end of the slide is bent, at right angles, downward, tocorrespond with the thickness of "the bumper, and upward as far as isnecessary to overcome the variation between high and low cars;

This slide is attached to the upper side of the bumper by means of ascrew or otherwise, and in such a manner that it can be moved backwardand forward, so that the pin can he'inserted into the hole in thebumper, and the slide drawn forward until the smaller part of theaperture in the slide is drawu into the creviceson, each side of thepin, at B. This, of course, will hold the coupling-pin in this positionuntil the slide is brought into contact with the bumper of anothercar,'when the slide will be driven back, so that the pin will dropthrough the larger part of the aperture in the slide, and also throughthe link which will have entered themouth of the bumper below.

Inorder to prevent the link from being driven back into the bumper, Ihave made it with two apertures, as given at O. 1 have also attached aspring to the back end of the link, in order to ,hold it level whenshoved back, and thus secure its entrance into the mouth of the bumper,which, of course, must be large enough to overcome the variation betweenlight and 1 loaded cars.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The coupling-pin B, notched as shown at B, in comhination with the slideA, constructed as described, for the purposes set forth.
